All Terrain Versatile Telescopic Fork Lift

ABSTRACT

Vehicles, systems and methods for providing articulating two section vehicles with tracks, and a front body attached superstructure with telescopic forklift, for use on all terrain condition applications. The vehicle can include front and rear track assemblies that can tilt up and down while traveling over different ground surfaces. Each of the track assemblies can have rotatable articulating/oscillating track wheels which can traverse different contoured surfaces. The right and left tracks on both the front and rear track assemblies can separately extend outward and inward from underneath the vehicles to add stability to the vehicles. The cab can be raised and lowered to add greater visibility for the operator. Hydraulics can be used for raising and lowering the extendable boom and operator cab, as well as controlling the body articulating hinge, the articulating tracks and the tilting controls for the front track assembly.

FIELD OF INVENTION

This invention relates to forklift vehicles, and in particular to vehicles, systems and methods for providing articulating two section vehicles each having track wheels with a front body attached superstructure with telescopic forklift, raiseable and lowerable boom, articulating tracks and tiltable track assemblies for all terrain condition applications.

BACKGROUND AND PRIOR ART

Common types of forklift vehicles have required the use of tire wheels to support the vehicle over ground surfaces, and often use fixed cabs. However, the use of wheel tires can and fixed cabs can cause different problems.

For example, the narrow width tires can cause the forklift vehicle to not be stable while traversing rough ground surfaces. Additionally, the tires wheels can sink into wet or soft earth and can cause the vehicle to sink and become stuck in the mud, etc. Additionally, sinking side wheels can allow for the forklift to topple over. These negative results from using tires can result in higher insurance costs based on accident damage to the forklift vehicles and operators/drivers as well as increased labor costs and the resulting down time to complete construction projects.

As for the fixed cabs, the driver/operator in the cab is limited to poor visibility conditions, since the cab is generally fixed in place on one side of the forklift vehicle. For example, this fixed location does not allow the driver operator to always be able to see conditions on the opposite side of the forklift vehicle. Having blind spots or limited visibility can result in the forklift vehicles having accidents.

Thus, the need exists for solutions to the above problems with the prior art.
